from time to time, for the prevention, abatement , and control of
pollution to the waters of the State, as authorized by the Act and the
Rules.
3. The Division, in the interest of permitting the operation
of a test plant for in-situ uranium mining (the "Test") for the purpose
of gathering information with which to evaluate full scale in-situ uranium
mining, and concurrently, protecting the State 's waters, imposes the
-2-
following technical conditions to modify the practices and procedures
proposed in the application,
(a) At least 10 days in advance of the commencement of
the drilling of any baseline sampling, monitoring, injection or recovery
well drilled, from time to time hereafter , by WMC in conjunction with
the Test, WMC shall submit to the Division for its review and approval
a tentative well location plan to a scale of 1 inch to 50 feet, indicating
the approximate location of such well.
(b) At least 72 hours prior to final well drilling and
completion of any well specified in 3 (a) , WMC shall notify the Water
Quality Control Division and the Water Resources Division of the
Department of Natural Resources and provide the Divisions the opportunity
to witness and inspect the well drilling and completion activities.
(c) For each completed well , WMC shall submit in duplicate
a well completion report including the following:
1. Lithologic log, geophysical log, and total depths.
2. Type of completion: perforation, open hole, screen.
3. Casing : size , type, grade, weight, setting depths.
4. Tubing/packer (if applicable) : size, type, name, model,
setting depth of packer.
5. Cement: class/type volume used. Describe and give per-
cent of all cement additives and slurry weight.
6. Cementing technique: pump and plug displacement through
casing is recommended to cement from the top of the
respective aquifer to the surface.
7. Cementing equipment : guide shoe, float collar, plugs ,
basket, etc, or equivalent.
8. Casing Centralizers : location and spacing.
9. Diagrammatic sketch of each type of well completion used.
(d) Following completion of wells WMC shall submit to the
Division, in duplicate, a final well location plan as in paragraph 3 (a)
above, indicating final surveyed locations of such wells.
(e) A minimum of 24-hour pumping test of the mineralized
zone shall be conducted prior to the injection of chemicals to determine
boundary conditions and any hydraulic interconnection of the Grover Sand ,
Porter Creek and Laramie-Fox Hills aquifers. The Fox Tills well to be used
--
in this test shall be located per paragraph 3 (i) oelow. Results of the
pumping test shall be provided to the Division with conclusion and
recommendations , substantiated by a mutually acceptable , independent
consultant at least one week prior to the planned injection of chemicals .
If the conclusion is that interconnection between aquifers does exist,
injection of chemicals will not be authorized and shall not proceed until
the interconnection is eliminated as required by the Division.
(f) Injection of chemicals shall be by gravity feed. WMC
may determine the fracture potential of the Grover Sand and the strata
overlying the Grover Sand. If found to be adequate to withstand in-
jection under greater pressure ; the Division, upon petition by WMC ,
may authorize an appropriate injection pressure .
(g) A map (scale 1" 50 ' ) indicating all exploration
tholes of record in the expected zone of mining influence shall be
submitted to the Division. Prior to the injection of chemicals ,
WMC shall purge the Test field by pumping formation water into the
injection wells at a pressure not to exceed 1S0 psi at the bottom
of the injection well for a period of 24-hours . The water purge test
shall be designed to detect any weeping at the surface which may re-
sult from incomplete exploration holes . All discovered leaks shall be
plugged.
(h) In addition to the monitoring wells in the mineralized
zone, the Test monitoring system shall include at least two shallow
monitor wells to be completed to the bottom of the first aquifer over-
lying the mineralization aquifer. In the plan view , these wells shall
be completed within the zone of mining influence defined as the expected
flow lines of leach solution from the injection to recovery wells .
Location of monitoring wells to be subject to approval of the Division.
(i) The Test monitoring system . shall further include at least
two (2) deep monitor wells . One well to be completed to the bottom of
the first aquifer immediately underlying the mineralization zone , and
the other monitoring well to be completed through the first aquifer of
the Laramie-Fox Hills formation. The location of the monitoring wells
shall be approved by the Division prior to construction . These monitoring
-4-
wells shall be cored to obtain representative core samples from the
aquifer being monitored as well as the interval or zone immediately
above the aquifer being monitored. These monitoring wells shall be
logged prior to completion. Coring and logging information will be
furnished to the Division in duplicate.
(j) WMC shall further include at least one deep
characterization well through the Laramie-Fox aquifer in a plan view
location outside the area of mining influence and outside the area
defined by the test monitor wells that are completed through the
mineralization zone. The deep drill hole shall be cored to obtain
representative samples and logged prior to completion as is necessary
to characterize the Laramie-Fox Hills aquifer and the integrity and
thickness of the interval between the mineralization zone and the
Laramie-Fox Hills aquifer.
(k) Prior to injection of chemicals, water quality
characterizations shall be established for the mineralization zone,
-the first overlying, the first underlying and the Laramie-Fox Hills
aquifers and for all monitor wells , as defined in Table 1 and Table
2 below. These characterizations shall be established by sampling
the completed monitor wells or designated sampling wells. To obtain
a valid sample the well shall be pumped until water is produced that is
essentially free of mud and foreign material and is essentially of a
quantity that evacuates the calculated volume of original free standing
water in the well casing. Further, characterization sampling (at least
4 samples) should span a period of time as long as practicable prior to
injection of chemicals, and multiple analyses should be run of each sample
to qualify variabilities. Water quality characterizations of the Laramie-
Fox Hills aquifer shall continue during testing. The characterization
of the Laramie-Fox Hills aquifer shall include continuous pressure monitor-
ing as is reasonably required by the Division.

(1) Water Quality characterizations shall be established for
reference water wells defined by WMC as "environmental" wells. The en-
vironmental well water quality baseline shall be established on the basis
of parameters identified as significant from the mineralization zone
water quality baseline list above (Table 1) . Accordingly, by definition,
mineralization zone sampling must be initiated first. At a minimum the
baseline assays for environmental wells shall consist of the following:
Alkalinity Phen (as CaCO3) • Nitrate (as NO3)
Ammonia PH

(m) Monitoring parameters are as specified in Table 2, in
paragraph 3 (k) , above, All monitor wells shall be monitored for these
parameters on a weekly basis commencing with the first day of injection.
A report illustrating the results of each such monitoring well since the
last report will be sent to the Division in duplicate the first week in
each month, except in the event of a significant change in one or more
of the monitoring parameters (a change unaccountable for by natural
variability or sampling error) , In the event of such a significant
change, the Division shall be notified immediately.
(n) In the event that a significant change occurs in a monitor-
ing parameter, as described in paragraph 3 (m) , above, WMC shall immediately
commence daily sampling, If the trend continues for seven (7) consecutive
days, WMC shall begin taking corrective action immediately and provide
a description of the corrective action procedures to the Division.
(o) Restoration parameters shall be based on the results of
site-specific groundwater analysis. Restoration to within 10 percent of
the average initial pretest water baseline value will be the standard
for restoration for TDS. When this value is achieved and the quality
of the groundwater within the mineralized zone with respect to the para-
meters set forth in Table 1, above, has been restored to a condition
approximating average baseline conditions, the groundwater shall be
considered restored, Accordingly, to accomplish this objective WMC shall,
prior to injection of chemicals (except as provided below in conjunction
with restoration testing) provide the Division with a written restoration
program which:
1. Decribes the restoration procedures proposed ;
2. Documents the effectiveness of the proposed
restoration procedure; and
3. Provides a restoration schedule.
It is recognized that initial in-situ test data of quantities larger than
core samples are desirable to identify such restoration procedures.
Therefore, WMC shall run a series of chemical slug tests to obtain the
desired information, Such slug testing is defined as injecting leach
chemicals into no more than two (2) different recovery wells as identified
for the proposed Test to allow leaching for a calculated radius not to
exceed 10 feet in any one direction from that well, at which time the
-7-
well will be pumped to remove the effected volume of water. WMC shall ,
nn the basis of this removed solution conduct restoration testing. On
the basis of these test results WMC shall submit the written program
as described above within two (2) weeks of injection of chemicals into
injection wells. During the period of evaluating the slug test
solutions, the slug test hole shall be monitored weekly and these
results provided to the Division. The restoration program shall be
subject to approval by the Division before proceeding with injection
and production of the test facilities.
In the event that any term or condition contained in paragraph
3 of this permit is found to be in conflict with WMC 's application,
which is incorporated herein by this reference, the terms and conditions
of this paragraph 3 shall govern.
(4) No solid waste shall be disposed of at the test site and
no liquid waste either directly or by surface water runoff from the test
site shall be allowed to flow to the Crow Creek drainage.
(5) As a requirement in the issuance of this Permit, and as a
condition for its continued effectiveness, WMC, acting as Principal there-
under shall furnish, within twenty (20) days after the issuance of this Per-
mit or before construction, which ever shall first occur , one or more
good and sufficient Performance Bonds in the amount of not less than
seventy five thousand and no/100 ($75, 000) dollars , with corporate
surety approved by the State, whereby said Principal and Surety shall
bind themselves, their successors and assigns, jointly and severally, to
the Colorado Department of Health for the use and benefit of the Division
of Administration for the faithful performance of restoration work in
accordance with paragraph 3 (o) of this "Permit for Subsurface Disposal
In Connection with Solution Mining Test Activities" as the undertaking of
Principal under said bond. Said obligations under this bond shall con-
tinue for such time and under such conditions as imposed by the Division
for satisfactory completion of the restoration program.
